I don’t think it necessarily needs to allow “stronger” decks, but just more cards gives more options, otherwise it just boils down to most cards likely gets the win.

Rather I would like to see more rules introduced on how to play.. More variation or even multi deck battles vs an opponent (say 3 decks back to back, with no duplicates across all 3 decks)...but then again it’s a super simple card game...so can’t go all magic the gathering with it.
